Missing non-local pseudopotential contribution

[Luca Sementa]

Dear Yambo developers

I’m doing calculations on metallic systems at RPA level. I produced the database for Yambo using pwscf. The problem is that Yambo don’t seem to find the non local correction of the PP. In the report file I always get the following warning : Missing non-local pseudopotential contribution.
Can you please help me to solve the problem?

Thank you in advance for your answer.
Best Regards.

Anyway, Luca, note that we are planning to implment the non-local commutator in PW ASAP. In the meantime, to evaluate the contribution of the non-local pseudo do a simple, as small as possible, calculation with abinit of the same system and compare the absorption (Independent particles is enough) with the one calculated using PW. You should see some change in the overall intensity that should not change even if you do more refined/converged calculations.
